Panasonic GX7 Test Video

13 April 2015 - 09:19 PM

My first 24p video with a Mirco four this camera




I found that the filter plus white balance gave me really good colour and as conditions were very bright I had no issues with noise

I used the inon UWL-H100 wet lens and I could zoom through with it.

I also tested the extended tele converter mode that gives 1.8:1 super macro with a close up lens

In hindsight I think the camera does such a good job with contrast and noise reduction that there is. I need to change the default settings as I had to add back contrast in the edit

I found the image quality of the compiled file better than my sony rx100 mark II on my tv but on YouTube the panasonic files seem to suffer more from re-compression

Anyway let me know what you think the video is not particularly fancy but just to give an idea of what can be achieved with wet lenses and micro four thirds

Fisheye Converter for Panasonic Lumix G Vario 14-42 X PZ

I bought this rather cheap converter for the 14-42 and test shots look pretty promising

I think Nauticam tried this combo with the 4.33" dome and 30 extension long time ago with the OMD-M5 but have not seen anyone using it

 

With a cost of £95 or $125 this is something to try before getting the 7-14mm Panasonic in my opinion as it is very cost effective and seem to wok well also at relatively wide apertures f/5-f/8

I thought of sharing few tips about the editing I do with my clips as I have had many comments about colors, contrast etc etc

Video Compression: my most technical article to date

04 February 2015 - 03:20 PM

Following on from the work I have done on checking what youtube does to your clips I have analysed how video is compressed real time before being saved

The full story is there but in essence:

 

1. Some brands have an edge on others when it comes to video compression i.e. Panasonic beats Sony why you can read it there

2. You need a bit more than 18% increase bitrate to shoot at double frame rate so that image quality is similar

3. Comparing two cameras intended for video use looking at sites like DXOMARK or dpreview can be misleading to say the least

 

 


The great versatility of the Lumix G X Vario 14-42 PZ and Nauticam 35 Flat Port

I am really excited by some testing I have done with this lens with wet lens (you can't use wet lenses with 4/3 cameras blah blah...)

If you are moving from compact cameras and have stock of wet lenses this is definitely something you should read before clicking the buy button
